In this study, the characteristics of a dominant strain wx3 isolated from the tissues of several sick red swamp crayfish were studied, and the immune response of the red swamp crayfish under stress was analyzed. The whole genome analysis of wx3 identified it as Aeromonas salmonicida subsp. ...

Pogostemon oil (PO) is a volatile oil extracted from Pogostemon cablin., a traditional Chinese medicinal plants. Clinical studies have confirmed that PO has broad-spectrum antibacterial activity, but the resistance and protective mechanism of PO against Streptococcus agalactiae (SA) infection in...

Nocardia seriolae is a pathogenic bacterium that commonly infects largemouth bass (Micropterus salmoides), causing chronic wasting disease characterized by multiple nodules. The mechanism by which Vitamin D3 (VD3) can resist Nocardia seriolae (N. seriolae)infection is unknown, although VD3 has been ...

Non-Saccharomyces yeast such as Debaryomyces hansenii or its cell wall-components are emerging candidates for novel functional aquafeeds, as they contain several microbe-associated molecular patterns (MAMPs) that can activate and modulate the host's physiological responses, thereby improving fish...

Marine bivalves include economically highly important aquacultured species worldwide (oysters, mussels, clams, scallops). Although one third of production in Europe is represented by mussels (Mytilus edulis, M. galloprovincialis) a significant decline has been observed in the last two decades,...

Photobacterium damselae subsp. damselae (PDD) is a dangerous bacterial disease that affects silver pomfret (Pampus argenteus) and its main virulence factors are pore-forming toxins. In this study, a highly pathogenic strain was obtained from naturally infected silver pomfret and was introduced into ...

The liver is one of the principle immune organs in fish, and involves lots of physiological processes. Pathological liver injury is a common symptom in fish farming caused by bacterial infection. Mannan-oligosaccharide (MOS) has been considered as a promising diet additive in aquaculture due to its ...

In this study, the effects of feeding diets containing tyramine (TA) to Litopenaeus vannamei at levels of 10 (TA10), 50 (TA50), and 100 (TA100) mg/kg on growth performance, immune parameters, hemolymph glucose and lactate level, biogenic amine synthesis, and resistance against Vibrio alginolyticus...

This study evaluated the vaccine-induced serological response after administering four commercial formulations containing Bovine Viral Diarrhea Virus (BVDV) type-1, BVDV-2, and Bovine Herpesvirus type 1 (BoHV-1) to young heifers with circulating maternal antibody titers. The study also determined...

Ethnopharmacological relevance: Echinacea purpurea (L.) Moench (EP) is a perennial herbaceous flowering plant with immunomodulatory effects. However, the immunomodulatory effects of EP on broilers after vaccination are still unclear. Aim of the study: The aim is to study the effect of EP and ...
